BIOLOGY
Topic : Cell structure and organization
A) the similarity in structure of animal and plant cell :





Cell membrane present
Cyctoplasm present
Nucleus present
Mitochondria present
Ribosome present
B) the difference in structure of animal and plant cell :
2) the function of cell membrane in controlling the passage of substance into and out of the cell :

Selectively controls the passage of substance entering and leaving the cell (selectively
permeable )
General rules : small molecules can enter easily . e.g water (osmosis) , water or
oxygen (diffusion)
3) the relationship between cell function and cell structure :

Root hair cell
1.It has long tubelur shape to increase surface
area for uptake water and mineral salt
2.It has a very concentrated cellsap in vocuale
3.
